When the composition. fuel have been thoroughly incorporated by suitable may chinery, the briquets made into any de sired form, preferably under such a, pres sure as the graded requirements of combusllie loriq'uets are then subjected to a process of final elimination of moisture, and simulteeemisly to e process of which the briquets are intended.

Also, that they possess a high calorific efliciency and preserve their form in the lire, the outer portion during corobustiou presenting of course some ash, which, however, is crowded off, but leaving the inner and unconsumed portions still herd enough to sustain the weight of fresh fuel above, and to preserve their form during slicing of the fire.

One of the chief reasons Why my i1uproved briquets are economical to manufacture that the chemiculsspecified so com bine as to reduce to the minimum the time and degree of heat applied to render them hard and Waterproof, the carbonizatiou of the carbohydrates of the molasses by the. sulfuric acid occurring at acomparatively low temperature. v

Cormn'inuted bituminous or soft coal made into briquets with my improved composition and treatment, is as hard as anthrscite coal, and burns without the annoy ing smoke nuisance usually resulting from the use of soft coal.

Briquets manufactured under my invention have the equivalent weight value of hard cos/l, but without cinder loss loco of the complete combustion of the bri I claim:

comminuted fuel and a composition including an insoluble, carbonized reaction prodnot of sulfuric acid, and molasses.

2. A waterproof briquet manufactured of comminuted fuel mixed with a composition containing an insoluble, carbonized reaction product of sulfuric acid, molasses and water, the said fuel and composition being mixed, shaped and baked.

3. A waterproof briquet manufactured of comminuted fuel, and an insoluble, carboni'zed reaction product of sulfuric acid and molasses rendered hard and waterproof by heat.

4. The method of making waterproof fuel briquets, consisting in mixing with comminuted fuel a composition containing an insoluble, carbonized reaction product of sulfuric acid, molasses and water, forming the mixture into briquets under pressure, and then subjecting the briquets to the action of heat to render them hard and Waterproof.

In testimony whereof I have affixed my signature, in presence of two witnesses.
